Beyond Prompt-Driven Architecture: Why LLM Systems Need Deterministic Workflows

Letting LLM prompts become your system runtime leads to non-deterministic, unmaintainable behavior—a major cause of agentic AI project failures. The solution is breaking workflows into discrete, typed steps with validation and control gates, where the model call is one component, not the entire architecture. This shift from prompt-as-runtime to structured pipelines is essential for production-grade AI reliability.
